Lucky 13 adjustable pump cone

[Ribs77]

I have the cobra fins and, while I generally don't go very fast, I've never encountered cavitation while turning at speed. Just during hole shot with lots of ballast or when hammering the throttle.

Edit: Basically what birddogdaze said. Maybe all you need is the fins if you're not getting cavitation on hole shot, but just during turns.

I'd be interested to hear your report after you install the Lucky 13 cone though!

Just to be clear, I don't experience cavitation going 20mph , possibly 30mph going into a turn. But I'm thinking I'm in the upper 30s and lower 40s when attempting it. Doing a very wide turn I would likely not experience it but trying to attempt a tighter turn is when I run into problems. In comparison from the yamaha to my speedster the cone on the speedster is twice the size; I'm not entirely sure it's stock because I purchased that boat in 2013 with only 10hrs on it. Anyways, I'll have the lucky 13 on by the end of the week and I have a 2 week boat trip that I stay on a lake starting the 2nd week in July. I'll definitely report back with feedback.
